I designed a facebook group banner and a LinkedIn banner and both are very blurry after uploading it to the platform. I know many people have this problem - maybe here is someone who really figured out a solution.
On both there is text and logos on it. I tried different formats like png, jpg, png-8 and png-24. I tried to upload it from mobile and desktop. I tried to make the texts and logos bigger. But still the compression of especially LinkedIn destroys the banner. It looked the same everytime: blurry.
Does anyone here know a way to really have sharp and clear banner pictures on social media? If yes, I would be super grateful for any suggestion!
